From what i remember (since i never tried them yet) all reactions i ever got when asking about flatwound strings was that they sound dull and whatnot. That they will not sound cool slapping yada yada yada. That they are good for jazz. Maybe the slap point is right, but while i was browsing the rotosound website to see what kind of strings they offer, i came across the steve harris signature set, which is a FLAT set. How can this be? Steve's tone is very bright and it pretty much sets the standard in metal bass tones (along with 2-3 others).. i was surprised to find out he uses flats! Whats your opinion with flats? What kind of music do you use them for?
